FreeBSD users BEWARE, this extension will not compile and install with the "pecl install paradox" command.

The configure script fails because it tries to use a library (libdl.a) that is available by default in Linux but not on FreeBSD. I had to alter the configure script and install the package manually.

I have reported this on the package page as a bug, but there does not seem to be any movement in maintaining this package, so I am posting this here for anyone having trouble trying to install this package on FreeBSD.
